原标题：四川：受地震影响的泸石高速公路有序复工工人师傅们正在对边坡开展震后检查等工作。　蜀道集团供图中新网成都9月13日电 (记者 刘忠俊 王鹏)记者13日从蜀道集团获悉，该集团所属四川路桥承建的甘孜州泸定县至雅安市石棉县高速公路(下称：泸石高速)10个标段中，已有9个标段陆续实现复工。         (ECNS) -- Hot days worldwide could experience around four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a study led by Chinese researchers.    Published in Nature Climate Change, the study found that traditional daily temperature indicators may overlook shorter periods of extreme heat, while hourly temperature analysis can provide a more detailed picture of heat exposure and associated risks.        Researchers from Sun Yat-sen University and other institutions analyzed global hourly temperature data from 1981 to 2023, combining observational records with climate model projections to assess how extreme heat exposure could change in the future.    The research team found that the duration of extreme heat increased by 62 hours per decade over the study period. Around 28% of extreme heat events occurred on days that would not have been classified as hot days based on conventional daily temperature indicators.    Under a high-emissions scenario known as SSP5-8.5, the researchers projected that between 2070 and 2099, each hot day could experience around four additional hours of extreme heat compared with the 2001-2023 period. Days not classified as hot could also see increased periods of extreme heat.    The study also found that low- and middle-income countries account for a disproportionately large share of both current and projected extreme heat exposure. Younger generations in low-income countries are expected to experience the greatest increase in lifetime exposure.    Researchers said the findings could help improve heat-warning systems, strengthen assessments of health risks and support climate adaptation efforts.    (By Helen Mo, intern Liu Shuangjing)                    。泸石高速是《四川省高速公路网规划(2019-2035年)》规划的重要组成部分，衔接京昆高速雅西段、雅叶高速雅康段两条川西交通大动脉。9月5日，甘孜州泸定县6.8级地震发生后，四川路桥迅速组织处于地震震中的泸石高速相关项目第一时间赶赴灾区开展抗震救灾工作，为保障灾后及时恢复生产，参与的抢险项目均已同步开展复工复产工作。
